Ciria Report 108 Concrete Pressure On Formwork -

): Measured in degrees Celsius at the time of placing. Lower temperatures delay the chemical hydration process, causing the concrete to remain fluid longer and exert higher pressure. Characteristic Stiffening Time (

Ensure all formwork tie-rods, clamps, and bracing elements match the structural drawing layout. High lateral pressures concentrate immense force directly onto these tensile components. ciria report 108 concrete pressure on formwork

) on vertical formwork. Detailed information regarding the report can be found at Concrete pressure on formwork (R108) - CIRIA ): Measured in degrees Celsius at the time of placing

While CIRIA 108 is widely used in the UK, other international standards exist: P_max should not exceed the full hydrostatic head

Note: This formula has upper and lower limits. P_max should not exceed the full hydrostatic head (ρgh) nor drop below a recommended minimum of about 25 kN/m² for normal pours.

Ensure the calculated empirical value does not exceed the pure hydrostatic pressure of the full liquid head. 4. CIRIA 108 vs. Modern Standards (DIN 18218 & BS EN 12812)
